FEED-WATER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 491,825, dated February14, 1893.

Application filed November 3, 1892- $erial No. 450,825- (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM V. WALKER, of Moravia, in the county ofCayuga, in the State of New York, have invented new and usefulImprovements in Feed-Water Apparatus, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

My invention relates to feed-water purifiers, adapted to be supported orsuspended within a boiler shell, and in which the water is primarilyheated so that substantially all of the impurities are precipitatedbefore the heated water is discharged into the water chamber of theboiler.

-My object is to improve the construction of the purifier, by connectingits sections by a tongue and groove joint and a lap of one under theother; by providing means whereby the discharge is broken up; and byproviding means whereby the surging of the water in the pan iscontrolled and the discharge regulated, particularly inlocomotives, roadengines or other portable boilers, while they are in motion.

My invention consists in the several novel features of construction andoperation hereinafter described and which are specifically set forth inthe claims hereunto annexed. It is constructed as follows, referencebeing had to the accompanying drawings, in which Figure 1, is atransverse section of a boiler, also showing, in end elevation thefeed-water purifier suspended therein. Fig. 2,is a side elevation of thepurifier, detached. Fig. 3, is a top plan of same. Fig. 4, is atransverse section of the precipitating pan, having notched edges online a: so without the inward flange. Fig. 5, is a like view of the samewith the flange and notched edges. Fig. 6, is a like View of the samewith the flange and without the notches. Fig. 7, is a top plan of partof the conduit portion enlarged. Fig. 8, is a vertical transversesection on line as, w in Fig. 7.

A, is a boiler shell having flues -aa all of ordinary construction. B,is the feed-water purifier consisting of a bottom, and vertical sidewalls creating a water receiver b-, a zigzag conduit -c and aprecipitating pan d, though the so I cut notches orotherwise serratethem as at p m, in order to break up the water as it flows over the topof the pan; In conjunction with these notches, or without them,I providethe top of the pan with the inwardly projecting flange -nwhich willprevent the water in the pan from surging and splashing over, when thepurifier is in a locomotive, road-engine or other portable boiler undermotion. The purifier is provided with an ordinary water induction pipe-r and blowoff pipe -w.

What I claim as my invention and desire to secure by Letters Patent, is

1. A feed water purifier constructed in sectional parts, connected bytongue and groove joints in their vertical walls.

2. A feed-water purifier consisting of sectional parts, having theirvertical walls connected by tongue and groove joints in their verticalwalls, and a flange on each section projecting under the adjoiningsection, and means to secure said flanges.

In witness whereof I have hereunto set my hand this 24th day of October,1892.

WILLIAM V. WALKER.
